Definitions
- Patented Apr. 11, 1950 FICE METHOD FOR PREPARING A FISCHER- TROPSCH CATALYST Max A. Mosesman, Baytown, Ten, assignor, by l mesne assignments, to Standard Oil Development Company, Elizabeth, N. J., a corporation of Delaware No Drawing. Original application December 20,
- This invention is directed to a method for preparing a composition adapted to be used as a catalyst. More particularly, this invention relates to a method for preparing a promoted cata-' lyst forutilization in the hydrogenation of carbon oxides.
- Catalysts containing promoters in substantially small quantities often permit consistently high conversion of the reactants to desired products over much longer periods of operation than is possible when using an unpromoted catalyst.
- a pertinent object of the present invention is to devise a method for preparing a catalyst particularly adapted for use in the Fischer-Tropsch synthesis.
- Another object of this invention is to prepare a catalyst that may be utilized in the synthesis of high yields of useful products by the hydrogenation of carbon oxides during long periods of operation.
- the present invention may be described briefly as involving the preparation of a catalyst comprising a major portion of iron or an iron oxide as the active catalyst material and a minor portion of alkali metal ferrate as the promoting material.
- alkali metal ferrates include potassium ferrate (K2FeO4) sodium ferrate and lithium ferrate.
- the present invention will be further illustrated by a method of preparing an iron oxide catalyst comprising an alkali metal ferrate promoter.
- a previously dried intimate mixture of one part by weight of fine iron powder and two parts by weight of potassium nitrate was placed on an iron plate anddistributed as a layer of approximately 2 centimeters depth.
- a second layer of approximately equal parts by weight of iron powder and potassium nitrate was then placed adjacent to the first layer. The second layer was then ignited and the reaction allowed to go to completion.
- a dense white cloud of volatile potassium formed which was removed from the reaction zone.
- the reaction product was cooled sufliciently for handling and removed from the iron plate and heated in a free oxygen containing atmosphere at approximately 1000 F. for about 4 hours.
- the reaction product was ground into a fine powder and pilled into one-eighth inch pills. Subsequent to the pilling operation, the pills were placed in a reaction chamber and reduced in the presence of hydrogen for 24 hours at a temperature of 700 F. and at atmospheric pressure. The hydrogen was passed over the catalyst at a feed rate of hydrogen of 1000 volumes per volume of catalyst per hour.
- The-catalyst prepared as described in the foregoing paragraph was then employed to synthesize hydrocarbons from an equal mixture of hydroen and carbon monoxide.
- the feed mixture of hydrogen and carbon monoxide was passed over the catalyst at a premure of p. s. i. g., a temperature of 575 F. and at a feed rate of 200 volumes per volume of catalyst.
- the catalyst prepared in accordance with this method of the present invention gives good yields of hydrocarbon and oxygenated compounds which may be obtained over substantial periods of operating time.
